SPECIFICATION forming part of Letters Patent No. 635,040, dated October 17, 1899.

Application filed June 29, 1899.

To all whom it may concern.-

Be it known that I, WILLIAM P. FINK, a

citizen of the United States, residing at Beury,

in the county of Fayette and State of WVest Virginia,have invented a new and useful Nut- Lock, of which the followingis a specification.

This invention relates to nut-locks; and it has for its object to provide a device of this nature in which the structure will be extremely simple and easy of manufacture and at the same time will be efficient in its operation, a further object of the invention being to provide means for enabling the ready removal of the lock.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in theseveral views, Figure 1 is a perspective view showing two beams crossed and secured together by means of a bolt the nut of which is locked with the improved device. spective view showing the lock illustrated in Fig. l in perspective. Fig. 3 is a perspective view of a second form of lock. Fig. 4 is a perspective view of a third form of lock. Fig. 5 is a plan view of the device shown by Fig. 3 and looking toward the opposite side.

Referring now to the drawings, 5 is the body portion of the lock, having a perforation 6 centrally thereof. At one side of the plate there is formed a recess 7, leading in the direction of the perforation 6, and from the inner end of which recess is formed a cut or slot 8 at an angle to the recess and passing at one side of the perforation, the resulting tongue 9 being curved upwardly, as shown.

The plate 5 at one side of the recess 7 opposite the free end of the tongue 9 is provided with an upward or outward arch 1O directly in line with the greatest outward eX- tent of said tongue, resulting in the formation of a chamber lying intermediate the lower face of the curved portion and the plane of the under face of the plate and which chamber is adapted to receive the end of a suitable tool in removing the plate from its active position.

One edge of the plate 5 is bent downwardly at right angles thereto, and, as shown in Fig. 1 of the drawings, this downwardly-extending portion lies against one face of the body 11 when the lock is in operative position, with Fig. 2 is a per-- Serial No. 722,310. (No model.)

the body portion 5 thereof upon the outer face of the body, which face lies at right angles to the edge or first-named face. This bent edge is for holding the plate against the support and preventing its rotation thereon.

When the lock is in operative position, a bolt is passed through the perforation 6 and has a nut thereon, the nut being screwed downwardly to engage the adjacent surface of the plate and the tongue 9, the plate and tongue being of spring material. As the nut is turned downwardly it first engages the tongue 9, engaging initially the highest point of the tongue in its path of rotation, the direction of the movement of the engaging portions of the nut being from the base. of the tongue upwardly, causing the tongue to rise and fall under the influence of the nut, which is angular, as shown. When the nutis finally seated upon the plate 5, it is disposed with one face thereof in a position to be engaged by the adjacent edge of the tongue 9, resulting from the cut 8.

When itis desired to remove the nut, a suitable tool may be passed beneath the curved portion 10 of the plate and operated to force the tongue 9 downwardly and hold it out of the path of rotationof the nut, when said nut may be readily unscrewed. When the nut has been removed, the same tool may be further manipulated to pry the look from the ca upon which it has been seated.

In Fig. 3 of the drawings is shown a form of the invention one end of which is curvilinear, two opposite edges of the plate 20 being bent downwardly to engage edges of the body to which it is to be applied, it being understood that these downwardly-turned portions act to prevent rotation of the lock.

, In Fig. 4 of the drawings is shown a lock.

comprising a plate 25, which is disk-shaped and has downwardly-projecting and sharpened points 26, which act to prevent movement of the look when it is used upon a wooden body.

While the shapes of the plates have been shown different in the several views, it will be noted that in each instance there is a perforation, a spring-tongue adapted to engage the edge of the nut, and an upwardly-curved portion for the purpose above described.

It will be readily understood that various other shapes of locks may be employed and that specific construction and arrangement may be otherwise varied without departing from the spirit of the invention.

Having thus described my invention, What I claim is A nut-lock comprising a spring-plate having a perforation therein, a recess leading from one edge of the plate and in the direction of the perforation, a slot leading from the inner end of the recess at an angle thereto and in a plane passing at one side of the perforation and resulting in the formation of a springtongue bounded on its outer sides by the edge of the plate and standing outwardly from the outer face of the plate, an outwardly-arched Vitnesses:
